Abstract

A sensor for determining and/or measuring alcohol which exhibits an electric conductivity which varies with the alcohol concentration, comprises a heater with a metallic-oxide semi-conductor body located in the range of the heater. A pair of opposite polarity electrodes are biased into engagement with the surface of the body by a spring clamping means. The semi-conductor body comprises a zinc oxide having a density which is close to the density of a monocrystal. The semi-conductor body is formed of zinc oxide and then sintered at a temperature above 750 DEG C and preferably at 1000 DEG C.
